Abstract bài trình bầy 

 

 

    “What I want to talk about is the problem of manipulating and controlling things on a small scale” stated Richard P. Feynman at the beginning of his visionary talk “There's Plenty of oom at the Bottom”, given on December 29th 1959 at the annual meeting of the American hysical Society at the California Institute of Technology. Today, half a century after this first insight into unlimited opportunities on the nanoscale, we still have to talk about the same ssue. The problem identified by Feynmann turned out to be a very difficult one because of a ack of understanding of the underlying phenomena of the nanoworld and because of a lack of uitable nanohandling methods. The talk by Prof. Sergej Fatikow addresses the latter issue.  

 

The handling of micro- and nanoscale objects with an accuracy in the nanometer range is an important current trend in robotics. It is often referred to as nanohandling and is primarily understood as manipulation of objects, which may include their finding, grasping, moving, tracking, releasing, positioning, pushing, pulling, cutting, bending, twisting, etc. Additionally, many other technologies requiring tool/probe positioning with an accuracy in the nanometer range are also regarded as nanohandling, e.g. material nanocharacterization methods like indentation or scratching; mechanical or electrical measurements on nanoscale objects; nano-structuring of surfaces by deposition or removal of materials, and others. Automated nano-handling is one of the key challenges of microsystem technology and nanotechnology. It will enable high-throughput manufacturing of novel products and open up new application fields.  

 

Current research activities in AMiR include, amongst others, the development of new nano-handling robots; the investigation of novel automated nanohandling strategies; the development of advanced control methods; as well as the investigation of suitable real-time sensing technologies on the nanoscale. In his talk, Prof. Fatikow introduces main approaches for handling objects on the nanoscale. He especially addresses his current work of an automated robot-based nanohandling station inside a scanning electron microscope (SEM). The latter serves as a powerful vision sensor and a work space for nanohandling robots integrated into the vacuum chamber and equipped with application-specific tools. Different research aspects of this work regarding the implementation of the main system components – the piezo-driven nanohandling robots, the control system, the vision-feedback approaches, and the force/tactile sensors – are discussed. Finally, current research projects and applications being pursued in

AMiR are outlined. They include automated nanoassembly of AFM supertips inside SEM, handling and characterization of carbon nanotubes (CNT), electron beam induced deposition (EBiD) as a bonding and nanostructuring technology, automation issues in AFM-based nanohandling, characterization of biological objects by AFM/nanorobots, and others.
